TALK ON

VCSELs and Green Data Com

Abstract: The energy required to transmit information as encoded optical and electrical data bits within and between

electronic and photonic integrated circuits, within and between computer servers, within and between data centers, and

ultimately nearly instantly across the earth from any one point to another clearly must be minimized. This energy spans

between typically tens of picojoules-per-bit to well over tens of millijoules-per-bit for the intercontinental distances. We

seek to meet the exploding demand for information within the terrestrial resources available but more importantly as a

common sense measure to reduce costs and to become stewards of a perpetual Green Internet. The concept of a Green

Internet implies a collection of highly energy-efficient, independent, and ubiquitous information systems operating with

minimal impact on the environment via sustainable energy sources [1]. A key enabling optical component for the Green

Internet is the vertical-cavity surface-emitting laser (VCSEL). Our research on energy-efficient VCSELs for applications

as light-sources for optical interconnects and for optical fiber data communication between 850 and 980 nm is reviewed.

We present VCSEL designs, design principles, and operating methods that enable data communication systems capable

of error-free operation at bit rates exceeding 50 gigabits-per-second with energy consumption approaching 50

femtojoules-per-bit @ 25 Gb/s. Yet unpublished results for 200+ Gbit/s optical interconnects based on wavlength

multiplexing are presented. Novel photon lifetime engineering [2] for reducing the energy consumption and increasing

the possible bit rate is presented. Optimum photon lifetimes and gain-to etalon wavelength offsets are shown to depend

on the target bit rate.In order to minimize energy consumption trade-offs between number of wavelength channels,

operating bit rates and modulation formats for given aggregated data rates have to be found.The importance of Si

photonics: integration with dedicated drivers based either on SiGe, CMOS or SOI technologies and novel fibers is

high-lighted..

Soliton separation from resonant background CW from a fiber laser

Abstract—Pulses generated in a fiber laser can be considered as solitons. However, solitons exist in conservative systems only. Pulses

generated in a fiber laser actually are a mixture of pure soliton and continuous wave (CW). Kelly sidebands are a resonant CW with

solitons. Therefore, it is difficult to separate CW especially Kelly sidebands from a soliton. In another word, pure solitons so far are not

obtained from a fiber laser. We propose an approach of soliton separation, by making nonlinear Fourier transform (NFT) on a steady

pulse generated from a fiber laser, then filtering out the eigenvalues of the resonant CW background in the nonlinear frequency

domain, and finally recovering the soliton by inverse NFT (INFT). Simulation results verify that the soliton can be separated from the

resonant CW background in the nonlinear frequency domain and pure solitons can be obtained by INFT. Soliton separation pave a

way for exploring soliton dynamics without CW background.

Recent progress of spatiotemporal mode-locked fiber lasers

Abstract—Spatiotemporal mode-locking, i.e., simultaneously locking of multiple transverse and longitudinal modes, is a general

form of mode-locking. Spatiotemporal mode-locked (STML) multimode fiber lasers are ideal platforms for investigating

Optical fiber micro resonators for laser and sensing applications

Abstract—Highly sensitive and wearable sensors are novel building blocks in the development of human-interactive system. These

attachable and flexible smart devices are commonly considered as the essential components in the next generation of

human-portable devices for remote diagnosis and treatment. Here, we report a simple architecture of ultrasensitive and wearable

photonic sensor which covers the detection of strain and pressure. The proposed sensor consists of a hybrid plasmonic microfiber

knot resonator (HPMKR) embedded in polydimethylsiloxane (PDMS), resulting in a PDMS-HPMKR-PDMS sandwich structure. A

gauge factor as large as 13,700 has been demonstrated in one direction and 794 in the other perpendicular direction of the device,

which is more than one order magnitude larger than traditional electronic devices. The experiments for sensing humans’wrist pulse,

respiration, and finger pulse are demonstrated. Finally, we will demonstrate its application in mode-lock lasers.

Abstract—A tapered-microfiber sensor near the dispersion turning point (DTP) is theoretically researched and experimentally

fabricated by carefully tapering a standard single mode fiber (SMF). With respect to other tapered fiber sensors, the microfiber sensor

near DTP has quite high sensitivity, which is verified by the theoretical analysis in this work. The influences of two critical structural

parameters, the tapering length and the waist diameter, on the occurrence of DTP are also studied. Furthermore, the preparation

technology of this sensor is experimentally explored. As last, the transmission spectrum of the fabricated microfiber DTP sensor is

highly consistent with that in theoretical calculation. These results show its potential for humidity sensing and other environmental

trace detection.

Characterization of Multimode Optical Fiber Transmission Matrix with Different Neural Networks

Fucheng Xiao, Yunxu Sun, Yan Meng and Xiaomin Zhan


Abstract—Multimode optical fiber (MMF) is a typical multi-scattering medium, through which light will produce speckles that

completely annihilate the original signal. But in fact, this distortion is only seemingly random, and the input and output of the optical

fiber have a deterministic relationship. Therefore, if a MMF is used as transmission medium, the response characteristics of the input

and output of the MMF must be known. It is proposed here to use different neural network to characterize the transmission

characteristics of MMF, which is also called the transmission matrix (TM). Different network fitting effects are expressed by the

reconstruction quality of the image.

Nanophotonic devices based electron tunneling effect

Abstract—Electron tunneling is a quantum-mechanical effect which allows the transport of electrons across a nanoscale junction

between two conducting electrodes. Here, by constructing tunnel junctions on the top of high-density Au nanorod array, we

demonstrated large-scale and efficient electrical launching of surface plasmons in the metamaterial based on inelastic electron

tunneling, which as well results in an eye-visible light emission due to the radiative decay of the plasmonic modes. By engineering

the geometrical parameters of the metamaterials, we can tune the tunneling-induced emission throughout the visible and

near-infrared spectral range. Moreover, by harvesting the simultaneously generated hot electrons from the elastic tunneling process,

we show that the light emission can be dynamically modulated due to the hot-electron-activated chemical reactions in the highly

confined junctions. Electrically-driven plasmonic nanorod metamaterial provides a fertile platform merging photonics and electronics

at the nanoscale, opening up opportunities for developing electron tunnelling-based devices, such as light sources, sensors,

optoelectronic memristors, and photodetectors.

Optimal control for stabilizing fringe phase in interference lithography

Sen Lu, Kaiming Yang, Yu Zhu, Leijie Wang, Ming Zhang

Tsinghua University

In interference lithography, the environmental disturbances will lead to a phase drift of the interference fringes during the exposure

process, resulting in a decrease of exposure contrast. Feedback control is usually used to stabilize the phase, and the choice of

control algorithm will affect the exposure effect. In this paper, a linear-quadratic-Gaussian (LQG) controller combined with a Kalman

filter is applied to provide an optimal feedback control by solving the problem of minimizing the variance of the residual phase


19

errors. The phase control method is described using a state-space approach. The simulation results show that the proposed control

method can effectively suppress the low-frequency phase drift, as well as the phase perturbation caused by mechanical vibrations.

VCSELs for 3D Sensing

Abstract—Vertical cavity surface emitting lasers (VCSELs) have long been predicted as low-cost enabling laser sources for many

applications including optical communications, sensing and imaging. The mirrors are typically distributed Bragg reflectors (DBRs) with

many tens layers of epitaxy layers with alternating refractive indecies. Since 2004, we invented a single layer high index contrast

near-wavelength gratings (HCG) to replace the hundred-layered DBR in a VCSEL structure. Snice then, we develeoped a new class of

planar optics has emerged using near- wavelength dielectric structures, known as high contrast metastructures (HCM). Many

extraordinary properties can be designed top-down based for integrated optics on a silicon or GaAs substrate. In this talk, I will

review recent results using HCG as mirror for VCSEL. I will discuss inventions and advances in VCSELs that have led to recent global

deployment of commercial applications including 3D sensing, LIDAR and optical coherent tomography applications. I will also discuss

Silicon nitride metasurfaces and their visible applications

Abstract—Optical metasurface is one kind of artificial planar structures. By designing the geometric configuration and specific

arrangement of subwavelength structures, metasurface can break through the performance limitation of natural materials, enrich the

physical optical behaviors, and can be used to the applications of portable planar photonics devices. As an emerging

CMOS-compatible material, silicon nitride has low absorption in optical band, which provides new impetus for the development of

high-efficiency large-aperture visible light metasurface. Here will give a brief introduction to the existing silicon nitride metasurfaces,

and show their visible applications of large-area high-resolution imaging, 3D integrated imaging, microscope meta-objective and

Mode-locked pulse generation based on black arsenic phosphorus in erbium-doped fiber lasers

Yiqing Shu, Jianqing Li, Leiming Wu, Zhitao Lin, Dingtao Ma

Abstract—Black arsenic phosphorus (b-AsP) is a novel two-dimensional (2D) material. It has aroused extensive interest in many

fields thanks to its excellent performance of broad tunability band gap and high carrier mobility. In this paper, 2D b-AsP ultra-thin

nanosheets were successfully prepared and systemically characterized. Under the influence of evanescent field effect, 2D b-AsP

nanosheets is successfully prepared as a fiber-based saturable absorber (SA). Mode-locked pulses based on 2D b-AsP SA are

generated in an Er-doped fiber laser, corresponding to the maximum repetition rate of 11.5 MHz and pulse duration of 807 fs. These

results show that 2D b-AsP has excellent application potential in ultrafast photonics and photodetectors, etc.

Electro-optical modulators based on silicon nanostructures with Mie resonances

Jiahao Yan

Institute of Nanophotonics, Jinan University

Abstract—The ability to dynamically modulate plasmon resonances or Mie resonances brings some advantages such as adjusting

the operating wavelength and modulating the optical signals. Electrically tuning as one of the most effective active tuning methods

can realize high switching speed and large tuning ranges. Also, the electrically driven optical devices can generate intriguing

phenomena in both the linear and the nonlinear regimes. Recently, electrically tuning plasmonic metamaterials have been widely

investigated where the modulation is realized through semiconductor layers, graphene, or electromechanical deformation. Noted

that, there are much few works about the electrically tuning on single nanoparticle level up to now, which is important for building

nanoscale functional devices. Conventional plasmonic materials have several disadvantages restricting their applications in

singleelement nanoantenna or metamaterial devices. First, plasmonic materials like gold and silver suffer from high optical loss at

visible range. Second, it is hard for plasmonic nanostructures to generate magnetic mode and tailor the optical field as we want.


21

Fortunately, dielectric nanoantennas can hold both electric and magnetic responses simultaneously and naturally. Therefore, this has

driven the intense search for high-index dielectric materials beyond noble metals. Silicon as a kind of high-index dielectric materials

has shown promising applications in metasurfaces, optical nonlinearity, and sensors. The magnetic resonant modes in silicon

nanocavities can be modulated through changing the sizes or crystallographic phases. However, how to realize active control of the

magnetic responses in silicon nanocavities has not been studied yet. On the other hand, silicon, as the premier material in the CMOS

technology, has been vastly adopted for the implementation of photonic systems to enable various on-chip optical functionalities

through the integration of optics and electronics. However, for the nonlinear optical devices, crystal inversion symmetry prohibits the

second-order nonlinear processes in silicon nanostructures. To circumvent this challenge, one promising technique has been

proposed through applying static electric fields, called electric field induced second harmonic generation (EFISH). Although this

phenomenon has been studied on microscale silicon waveguides, how to electrically control the nonlinear signals of silicon

nanocavities still remains unsolved. In this work, we realize the electrically controlled Mie resonance-based linear and nonlinear

optical responses of individual silicon nanostructures in the visible range through changing the applied voltage. For linear scattering

signals, we observed that the plasmon-dielectric hybrid resonant peaks experience blue shift and obvious intensity attenuation with

increasing the bias voltages from 0 to 1.5 V. A physical model has been established to explain how the applied voltage influences the

carrier concentration and how carrier concentration modifies the permittivity of silicon and then the final scattering spectra. For

nonlinear signals, our experiments reveal that the application of a static electric field transduces the large third-order susceptibility of

silicon into an effective second order process that facilitates the generation of frequency-doubled signals via the EFISH process. Our

findings bring a new approach to build excellent tunable nanoantennas or other nanophotonics devices where the optical responses

can be purposely controlled by electrical signals. Keywords:

Abstract—Humidity sensors are important devices that have been used extensively in our daily life. ZnO material exhibits excellent

performance in the field of humidity sensing, most of which are based on changes in resistance under different environments. In this

Biomedical imaging leveraging light and sound

Abstract—Based on the energy conversion of light into sound, photoacoustic imaging is an emerging noninvasive biomedical

imaging technique and has experienced explosive developments in the past two decades. As a hybrid imaging technique,

photoacoustic imaging possesses distinguished optical absorption contrast as in optical imaging and superb spatial resolution as in

ultrasound imaging. It can visualize biological samples at scales from organelles, cells, tissues, organs to small-animal whole body

and has found unique applications in a range of biomedical fields. In this talk, I will present our most recent progress in

photoacoustic imaging, including photoacoustic tomography and photoacoustic microscopy. In photoacoustic tomography, I will

present our efforts in the development of a high-performance, real-time photoacoustic scanner and its applications in the sentinel

lymph node identification in vivo. Results reveal that the detector view angle, element number, center frequency, bandwidth,

aperture size, focusing, orientation error, and scan step angle error all have significant impacts on the imaging performance of the

scanner. The developed scanner can be used in practical scenarios and produce real-time high-performance imaging. In

photoacoustic microscopy, I will report our work in single cell and single vessel imaging. Results show that optical-resolution

photoacoustic microscopy can not only achieve high-resolution, high-sensitivity single cell imaging but also can visualize blood

vessels architecture of the retina and choroid in living rabbits without any labeling. The work advances both the technology and

applications of photoacoustic imaging in biomedicine.

In vivo hybrid-contrast tomographic imaging by Magnetic Resonance Imaging and Photoacoustic Tomography

Shuangyang Zhang, Xipan Li, Zhichao Liang, Jian Wu, Shixian Huang, Zhijian Zhuang, Yanqiu Feng, Qianjin Feng, Li Qi, Wufan Chen

Southern Medical University

Abstract—Photoacoustic tomography (PAT), as an emerging biomedical imaging technology, is capable of obtaining the distribution

map of deeply seated optical absorbers with high spatial resolution and temporal resolution. This functional imaging method has

been successfully used in pre-clinical and human studies, including tumor screening and response to treatment. Magnetic resonance

imaging (MRI), with a multi-parameter contrast mechanism, can provide excellent anatomical soft tissue contrast with similar spatial

resolution as PAT. The image contrast of PAT and T2 MRI is derived from the absorber concentration and proton relaxation velocity

respectively, one carries functional information and the other provides structural information. Combining the strengths of these two

complementary imaging modalities will provide reliable anatomical background information for better visualization of absorber

distribution.

Here, we present a method for the acquisition and co-registration of PAT and MRI data in in vivo animal studies. Our method

includes a novel dual-modality animal imaging bed and a robust dual-modality spatial co-registration algorithm. The dual-modality

animal imaging bed consists of a gas tube, a breathing mask and a solid animal support that can be separated into two parts, one for

PAT, and the other for MRI. This ensures that the animal maintains at the same posture while switching between the two imaging

modalities. The spatial co-registration of the PAT and MRI images is divided into 2 steps. Step 1: Axial co-registration: before

imaging, the surface of the mouse is marked with black Chinese ink, which can be visualized on both PAT and MRI. The

corresponding position of the cross-sectional image can be located by analyzing the images with peak intensity on the tissue surface.

Step 2: Transverse co-registration: rigid co-registration algorithm based on mutual information is used to precisely align the

dual-modality images after the background is removed. This method can be applied to the entire body of the animal, including the

head, lung, and abdomen.


23

In this work, we have demonstrated the feasibility of an image acquisition and co-registration method for PAT and MRI. The design

of the dual-modality animal imaging bed ensures that the deformation of the animal is within acceptable range when switching

imaging modalities, thereby simplifying image co-registration. The dual-modality hybrid-contrast image obtained with our method

simultaneously provides functional and structural information. This simple and reliable method can be widely applied to in vivo

animal pre-clinical studies that used PAT and MRI.

Multispectral Photoacoustic Tomography with a New Sparse Sampling Scheme

Xipan Li, Shuangyang Zhang, Jian Wu, Shixian Huang, Qianjin Feng, Li Qi and Wufan Chen


Abstract—Multispectral photoacoustic tomography (PAT) is capable of resolving tissue chromophore distribution based on spectral

un-mixing. To cut down the data volume for multispectral acquisition, sparse sampling methods that reduce the number of detectors

have been developed, but their image reconstruction is challenging because of insufficient angular coverage. During spectral

un-mixing, these inaccurate reconstructions will further amplify imaging artefacts and contaminate the results. In this work, we

present a new sparse sampling method, which we termed interlaced sparse sampling (ISS) PAT, to solve the above problem.

The proposed ISS-PAT method is based on a rotation-scanning imaging mechanism, which requires only a few transducers. Assisted

with a specially designed image reconstruction algorithm, ISS-PAT achieves comparable performance to that using large number of

transducers while keeping the total image acquisition time unchanged.

Measuring the space-variant point spread function for photoacoustic image deblurring

Jian Wu, Xipan Li, Shuangyang Zhang, Shixian Huang, Qianjin Feng, Li Qi, Wufan Chen

School of Biomedical Engineering, Guangdong Provincial Key Laboratory of Medical Image Processing, Southern Medical University,

Guangzhou, Guangdong, China

Abstract—The spatial resolution of photoacoustic tomography (PAT) can be characterized by the point spread function (PSF) of the

imaging system. Deconvolution of the images with the PSF has been shown to be able to restore image resolution and recover object

details. However, due to its tomographic detection geometry, the PAT image degradation model should be described by using

space-variant PSFs. Previous PAT approaches missed this inherent imaging characteristics and resolution restoration remains

challenging. To solve this, we propose a PAT image restoration method to improve image quality and resolution based on

experimentally measured space-variant PSFs.

In this work, we have designed a rigorous measurement procedure of the space-variant PSF for PAT and proposed an iterative

deconvolution algorithm to correct for the resolution degradation. Phantom experiments were performed and the results showed

significant image quality improvement.

Automatic initial rotation angle error correction for endoscopic airway OCT improves 3D structural reconstruction

Zhijian Zhuang, Shuangyang Zhang, Xipan Li, Jian Wu, Shixian Huang, Qianjin Feng, Li Qi and Wufan Chen


Abstract—Endoscopic airway optical coherence tomography (OCT) is a cross-sectional imaging modality that can detect the airway

contours for high-resolution 3D reconstruction. During imaging, the endoscopic probe mechanically scans the airway, thus the

acquired images inevitably suffered from the initial rotation angle error (IRAE). IRAE is one of the results of nonuniform rotational

speed: when the probe scans the airway to form each frame, the initial rotation angle is slightly different. This leads to structural

distortion when performing 3D reconstruction and visualization of the airway.

Point-of-care Chemiluminescence Immunoassay Centrifugal Microfluidics for Gastric-17 Detection

Yang Minghao, Liu Kangkang, Yang Jiachen, Wang Guanghui

Nanjing University

Abstract—Gastric cancer is the one of the most common malignant disease worldwide that causes death. Serum gastric-17 (G-17) is

considered to be a serological marker of gastric cancer. The difficulty of treatment is strongly depended on discover time. It is very

important to develop a fast, accurate, low-cost and portable early diagnosis method. The lab-on-a-disc (LOAD) or centrifugal

microfluidics platform introduces the centrifugal force generated by chip rotation under the driving of micromotor. LOAD is

pump-free, providing the best way for multiple parallel operations, which is a good choice for early screening of gastric cancer. In

this paper, we present a fully automated lab-on-a-disc for simultaneous detection of G-17 from whole blood based on magnetic

enzyme chemiluminescence immunoassay. Serum extraction, metering different concentration ratio and fitting of standard curve can

be realized on disc. There is a good linear correlation between chemiluminescence signal intensity and G-17 concentration over the

entire measurement range (0-256pmol/L), and the detection limit is 2.11 pmol/L, which has great potential for point-of-care (POC)

with high sensitivity and good repeatability.

Research on the measurement of heart rate based on LD laser and multimode fiber

Xiaomin Zhan, Yunxu Sun*, Fucheng Xiao, Yan Meng, Jianyu Zhang


Abstract—A micro-vibration fiber sensor for the measurement of human heart rate is proposed and experimentally demonstrated.

The specklegram generated at the end of the multimode fiber depends on the applied disturbance along the fiber and thus can be

used to detect the heartbeat signals. The sensitivity of vibration sensor based on fiber specklegram is highly sensitive to the

multi-mode fiber diameters, which has been experimentally explored in this work. A multimode fiber with an appropriate diameter is

selected to achieve a relative high sensitivity in vibration sensing. At last, the selected multimode fiber is utilized to measure the heart

rate of the human body. By processing the detected specklegrams, a clear heartbeat signal curve is obtained, which shows potential

application value in health monitoring.

New ATP Approach for optical wireless communications

Abstract—Acquisition, tracking, and pointing (ATP) mechanisms are generally adopted for optical wireless communications (OWCs)

to maintain a strict alignment state for reliable communication. ATP mechanisms conventionally employ beacon lights to determine

the orientation of the remote optical terminal. we consider a visual tracking approach where metrics based on target imaging rather

than the received beacon signal are used for steering the gimbals and/or mirrors to aim at the target. A traditional beacon uses a di

rectional light source, which can only be detected at an extremely limited angle. The proposed method adopts a new shape beacon,

which can be captured at a wide angle, and hence is much more suitable for mobile applications, such as vehicle-to-infrastructure,v

ehicle-to-vehicle, station-to-plane, and plane-to-plane communications.

A few-mode fiber based Beamforming System

Abstract—In this paper, a novel beamforming system based on few-mode fiber is proposed. The beamforming architecture is

consisted of single wavelength laser, photonic lanterns (PLs) and planar array antennas composed of cascading few-mode fiber loop

TTD units and single-mode fiber loop TTD units, both of which are controlled respectively by 2 × 2 optical switches. Beam steering

in the azimuthal dimension is provided via TTD lines with the identical mode. The mode diversity is brought to act as multiplying

channel. Beam steering in the elevational dimension is provided via TTD lines between different modes. This novel beamforming

system can realize 2D beam steering d under a single wavelength, which overcomes the high cost of tunable lasers in traditional

beamforming system integrated with wavelength division multiplexing (WDM) technology. Moreover, the system structure is greatly

simplified by adopting the mode dimension of few-mode fiber. We have made a proof-of-the-principle demonstration of 3 × 3

delay line matrix with a unit time delay of 6 ps in the elevational dimension and a unit time delay of 12.4 ps in the azimuthal

dimension for two-dimensional steering. The experiment results demonstrate the feasibility of the proposed scheme.

Recent Advances on Optical Wireless Communication Technologies for 6G

Abstract—We will review our latest progress on the micro/nano devices-based optical wireless communication (OWC) development

that is aiming for 6G. The light sources are critical for OWC and we will focus on presenting our new results on system applications

based on micro-light emitting diodes (micro-LEDs) and vertical cavity surface emitting lasers (VCSELs). In addition, high-speed,

multi-user and diffuse communications have become distinctive features of next generation 6G OWC systems. Different

high-performance OWC systems in various application scenarios based on micro/nano devices will be discussed. For micro-LED, we

firstly propose a high-speed and multi-user OWC system using OFDMA in the typically indoor environment which can support

maximum 6 users for communication, simultaneously. Then we will present an underwater OWC system which has the highest system

bandwidth distance product among current existing single-pixel LED-based underwater OWC systems. For VCSEL, our research

shows that a diffuse OWC system which can provide high-speed access while maintaining a large coverage area. In addition, we

demonstrate various high-speed and multi-user VCSEL-based OWC system using Code-OFDM, OFDMA and NOMA. Furthermore,

we further design a novel modulation format, and implement machine learning and deep learning technologies for upcoming OWC

systems. Finally, we will also discuss some future technologies and perspectives on the OWC for future 6G applications.

Abstract—Coherent anti-Stokes Raman scattering (CARS) microscopy permits vibrational imaging with high-sensitivity, high speed,

and three-dimensional spatial resolution. SF-CARS is a kind of spectral-scanning single-frequency CARS imaging system with

versatile spectroscopic capabilities, especially when coupled with broadband laser sources. Here, we implement

spectral-focusing-CARS hyperspectroscopy to characterize lipid and protein in pork samples. For hyperspectral CARS imaging, the

femtosecond pump and Stokes laser beams are chirped by using SF-57 glass rods with the lengths of 40.5 and 54 cm to generate the

2 ps pump beam and 1.8 ps Stokes beam, respectively, before they are combined onto a dichroic mirror. The results show that the

CARS spectrum is consistent with the spontaneous Raman spectrum, and the ratio between CH2(2850cm-1)/CH3(2930cm-1)

functional groups is high in lipids, on average >10, consistent with the literature, the peak ratio is on average
